Securing Security Bracket

Use a #8 x 3/4" pan head screw.

Thanks for posting. These brackets are replacement hardware for Capitol doors; is that what you have?

These brackets clip onto the back end of the stationary door, and one end locks onto the door frame. The screw hole lines up with those in the door itself. It is used with our 80-002 door bumper, which gives the door something to rub against.
